Are the 8 slot adding items permanent,

or are they only for an event?

One would think "permanent":

1. The eight slot items are in the regular cash shop section
2. The eight slot items are not in the event section

Just wanted to make sure. lol

Just wondering, what is this item? Not trying to sound nub or anything but I haven't heard of this item at all.

They are like on the first page of the cash shop. Kind of hard to miss, if you use the cash shop that is.
